[Elecraft] Using the k3 for WSPR

I don't have a K3, but I operate JT9 and JT65 with a K2. If youuse the 
K3 in USB mode, then it works the same way as it does for the K2. By 
convention, the subbands are specified as VFO frequencyon USB. On30 
meters. the subband is 10.130. You just leave the VFO (receive) on that 
frequency. When the software modulates the signal in transmit, tones are 
produced based on the VFO frequency. The transmit frequency doesn't 
change per se. But the modulation causes sidebands to be generated above 
the VFO frequency which are the WSPR mode tones. Everything is based on 
the VFO frequency. In fact, under rig control like HRD or omni-rig, the 
WSPR software presets your rig to the convention-defined subband VFO 
frequency.

For those of you using the K3 does your read out on the K3 change to the TX freq then the rig goes into transmit? Mine is not and not sure if this is normal or if I have to set something to show this.
